I thought Brian did ok with Scooter, after listening to it again, its a little high and close to being like Sal. But still its good to have this charcater back in action again.
Yes Matt Vogel did do the voices for Janice and Scooter in Racemania, and yes I know for a fact that he dons the bird's suit everyonce in a while.
On the topic of voices, I think thats the one thing people will be picky about in this film. Sure it will take a little getting used too, but we have to give John, Eric, and yes even Brian, a chance to get the feel for these chrarcters, it took Steve a while but I think he finally has Kermit nailed now. It wont look good if all of us fans are complaining that someone doenst sound quite right, we should be supporting the Henson Co. and this movie to make sure these guys will back again & again.
Sorry to stand on a soapbox with this, but that was my 1st reaction when watching the movie, and I hope that everyone doesent pick it apart, and just appreciate it for being a new Muppet movie, and hopefully the kickoff for a era in Muppet History.
